Blood markers may flag delirium risk in elderly surgery patients
NCT ID NCT07411612
First seen Jun 26, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study is looking at whether certain substances in the blood can help predict postoperative delirium—a state of confusion that can occur after surgery in older adults. Researchers will measure specific biomarkers before and after surgery in 1,170 patients aged 65 and older undergoing major non-cardiac, non-brain, and non-vascular surgery. The goal is to find a reliable way to identify those at risk early, which could improve monitoring and care.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
- What this could lead to
- If successful, this study could help identify patients at high risk for postoperative delirium using simple blood tests, allowing for earlier monitoring and preventive care.
- What could go wrong
- This is an observational study, not a treatment trial. It will not test any intervention, and the findings may not lead to immediate changes in patient care. The results are still uncertain.
